Given these symptons the most likely explaination is that either
there is not a "mythbackend" process running on the slave machine
or if it is running it is not connecting to the master properly.

In a shell on the slave machine, run:

$ mythbackend
Running as a slave backend.

Verify that you see both "Running as a slave backend" and "Connecting
to master server". The master should also announce that the slave
has connected and "found changes in the todo list" to rework the
schedule for the current number of cards.

All frontends connect to the master at first but if playback is
a file on a slave then it will open sockets for control and data
from the slave.
